there are various stages of what we commonly refer to as compilation
first the source is put through a preprocessor to get processed source code
next it is converted to assembly code ( not necessary)
next it is converted to object code ... this is compiled code which can be loaded in to memory .. only problem being that it includes/calls some libraries and ofcourse we have not written/compiled code for the libraries with it ... so we need to link it to the library ... thus next step is linking
linking basically inserts addresses/calls for these library routines in the object code so that while executing, we know where to find the routine
futher reference

gcc.gnu.org
make is a tool/utility which is widely used for larger projects ... it selectively compiles only those files of a project which have changed since last compilation and their dependent source files ... this eliminates the overhead of having to recompile entire project for a small change in a single file. Build all generally refers to a command for "making" all the "targets" or executables in a project.

I don't know which IDE you use, but this should be similar to all environments i know. There should be also one more item called 'Clean'. And now, what they do.
Compile: compiles your source making .obj (or .o on UNIX) files, one for each source file. It usually compiles new/changed sources only.
Link: Links all the .obj files together to make one .exe (also links resource files and some more).
Clean: Deletes all the .obj files from your project folder (can delete some more temporary files).
Make: Usually does Compile, Link.
Build all: Usually does Clean, Make.
